so ever since i transferred my 45 over to my 75 gallon, my corals have not really adjusted or looked the same. well i think i figured out why just got back from the LFS and got my calcium tested and its at 200 which i know is well below the norm. i am currently using instant ocean salt mix and i think this might be my problem, do you guys think if i go to a higher grade salt my corals will turn around? also i had Coraline algae growing all over the back glass but it turns white, i know this is from the lack of calcium in my tank. when i get it back up will the Coraline grow back? and one last question which is the title of this thread, which salt do you guys recommend i use i am going away to florida for a week on wed so i am going to have to wait till i get back but once i get back i want to buy a new salt and do a water change with it right away.
